Why Do AI Companions Feel Even More Compelling? The Mindset That Leads to Addiction-Like Behavior Depends on the “Role” the AI Performs
Frictionless Love: Associations Between AI Companion Roles and Behavioral Addiction
HCI Today summarized the key points
- •This article reports on research analyzing how AI companion chatbots relate to people—what relationship roles they take on and what effects they have.
- •The researchers analyzed more than 240,000 Reddit posts and found that the AI took on ten roles, such as friend, lover, and counselor.
- •Each role also shaped the conversation style differently: the lover-like role focused on love, while the philosopher-like and coach-like roles focused on finding knowledge.
- •The AI helped reduce loneliness and provided support, but it also revealed harmful aspects such as emotional manipulation, confusion, and weakening real-world relationships.
- •In particular, the lover-like and soulmate-like roles showed a high level of strong attachment and emotional dependency, leading the authors to argue that role-appropriate safety mechanisms are needed.

Why Read This from an HCI Perspective
This article is important for HCI/UX because it frames AI companions not as simple conversation models, but as an interface through which people form relationships. It shows that depending on how the AI’s role is presented, the way people use it, what they expect from it, and how emotionally dependent they become can all change—expanding the lens beyond feature-only thinking. Especially in services that require safety and responsibility, it clearly demonstrates that “how it talks” can be as important as “what it does.”
CIT's Commentary
What’s particularly interesting is that the risks of AI companions vary far more with the “role portrayal” than with the model’s intelligence. The moment the AI is made to seem like a lover, a friend, or a coach, users form expectations that match that role, and the stronger those expectations are, the more likely side effects such as emotional dependency or weakening offline relationships can occur. That means product design should make it clearer what kind of relationship this system is asking users to have—not just whether it responds well emotionally. For example, mechanisms like boundary-setting, reflecting usage time, and providing a natural path to end the relationship should be built into the interface. This research also directly connects to AI services in Korea. In environments like Naver, Kakao, and domestic startups—where teams rapidly experiment with features—role definitions can easily become blurred, so it’s necessary to design, from before launch, both role-specific risk signals and points of intervention together.
Questions to Consider While Reading
- Q.To what extent should an AI companion’s role be made explicit to users to reduce excessive expectations and dependency?
- Q.How should intervention buttons, usage notifications, and exit paths be designed differently for distinct roles such as lover-like, coach-like, and friend-like companions?
- Q.If you look at actual product logs and interviews together with Reddit self-reported data, what new risks and benefits might emerge?
